The problem

MMM has always been out of reach

The biggest brands in the world have used Marketing Mix Modelling for decades to understand exactly what's driving revenue. Everyone else has been locked out — until now.

  • $200K+ agency fees — traditional MMM engagements cost a fortune and take months to deliver insights that are already out of date.
  • Black-box outputs — agencies hand you a PDF. No way to rerun the model, adjust priors, or explore what-if scenarios yourself.
  • 12-week delivery cycles — by the time you get results, the market has moved and your media plan is already wrong.
How it works

From spreadsheet to strategy in three steps

No data science team required. No six-figure retainer. Just your media data and a browser.

01
Upload your data

Drop in your weekly media spend CSV — TV, Paid Search, Social, Display, whatever channels you run. Our automated quality engine scores your dataset across 5 dimensions before any model runs.

02
Run the model

Choose your engine — Google Meridian or Meta Robyn. Open Model handles priors, MCMC sampling, convergence diagnostics, and adstock decay. You just press run.

03
Act on insights

Get channel ROI, marginal ROI, budget optimisation recommendations, and geo-holdout incremental testing — all in a live dashboard you can share with your team.

What's included

Everything you need. Nothing you don't.

Automated Data Quality Scoring

5-dimension quality engine scores your dataset 0–100 across completeness, multicollinearity, variance, anomalies, and provenance — before a single model parameter is touched.

Dual MMM Engines

Google Meridian (Bayesian, NUTS MCMC) and Meta Robyn (Ridge Regression) — automatically selected based on your data quality score, or override manually.

Live ROI Dashboard

Channel revenue decomposition, total vs marginal ROI, response curves, and budget optimisation recommendations. Real-time, not a quarterly PDF.

Geo-Holdout Incremental Testing

Design and analyse geo lift experiments to validate your MMM predictions with real-world causal lift. Close the loop between model and reality.

Pricing

A fraction of the cost.
All of the rigour.

Leading Bayesian MMM platforms start at $2,900/month. Traditional agency MMM engagements run $4,000+/month effective cost. Lock in founding member pricing now — permanent, for life.
